6.6.1 on Ultra 6 Loses DNS lookup after a few days

This time the unit locked up so I had to reboot it. I set the IP back to DHCP. Running your other command I noticed that I had not updated my NTP address and that the 2nd ethernet connection had a router and DNS entry set that it cannot connect to. I have Eth1 directly connected to a PC with a cross over cable. I removed the router and DNS entries from that connection. I am wondering if that was the issue??? How are the network connections weighted? Which link will it try by default? I see they are both listed as favorite.

Once I removed that Router and DNS entry from Eth1 I could no longer resolve DNS So it really seems like it wants to use that link

root@NAS:~# ping google.com
ping: bad address 'google.com'
root@NAS:~# ping 8.8.8.8
PING 8.8.8.8 (8.8.8.8): 56 data bytes
64 bytes from 8.8.8.8: seq=0 ttl=46 time=9.523 ms
64 bytes from 8.8.8.8: seq=1 ttl=46 time=9.473 ms

So next I disconencted Eth1 and then I could ping again. Any ideas on how to have the two connections used but favor Eth0 for internet and DNS?
